May Parker is the daughter of Spider-Man and Mary Jane. Formerly Spider-Girl, May bonded with the Venom symbiote and became a heroic new Venom. However her father, already traumatized by the death of his wife, was horrified that May was Venom. Accusing her of "sleeping with the enemy", Spider-Man and May became estranged and he rebuffed every attempt by his daughter to reconcile. It wasn't until he saw May fighting heroically as Venom during a massive battle that he accepted his daughter and the two became a family again.
